I No. 815,309.

' Be itknown that I, ADOLPH PLAGMAN, a

' citizen of the United States, and a resident of Davenport, in the county of Scott and State "of Iowa, have invented certain new and use- "ful Improvements in Mechanical Movements, of which the-following is a clear, full, and eX- act description.

My invention relates to mechanical movements, and particularly'to mechanism for "converting a continuously-revolving movement into a rotary reciprocal movement,

such as is now extensively used for what rotary wash ng-machines,. churns, &c.

are known as The object of my invention is to transfer the manual or other actuating power from. the drive-wheel of a machine of this kind to a point nearer to or directly connected with the rotary reciprocal parts of the same, and thus, among other things, enable the operator to derive the advantage which results from the use of the momentum or inertia of thecontinuously-revolving drive-wheel in;

- This I accomplish by the means hereinafter fully described, and as running the machine.

768,342, and comprises. a continuously-re- 'volving drive-shaft a, suitably journaled in a suitable frame A of suitable design. The

outer end of this shaft a has a fiy-wheel B mounted thereon,and its opposite end has a pinion G secured thereto that meshes with a segmental rack (1, carried by and projecting from a rocking yoke D. Yoke D is pivotally connected to the ends o'f'thecurved por- ,tion of a segmental rack E by means of inwardly-projecting trunnions h h, and this rack is supported in the same plane as the shaft a by arms K K, projecting in diamet MECHANICAL'MOVEMENT.

from and engages the elliptical inner edge of a guide-frame g. Guide-frame g is secured at about its center of length to the vertical end portion of frame A opposite the end thereof-in which the bearings for the shaft a are made and is given a curvature which is struck from the center .of the hub f of the segmental rack E. When the shaft'a is reved, pinion C through its engagement of the rack d imparts to yoke D-a rotary reciprocal movement, and by virtue of the engagement of the antifriction-roller G with the guide-frame 9 causes the yoke D to rock up and down, so as to enable the pinion to engage first the upper and then the lower side .of the rack dto produce said rotary reciprocal movement. The rack E is provided with internal teeth e, which mesh with a pinion F,

secured to the vertical rotary reciprocal shaft H intermediate its bearings in the horizontal reaches of the frame A.

The description of the mechanism thus far described has been confined to thegearing forming the subject-matter of my aforesai My invention relates to -means which are applied directly to the segmental rack E. This means consist of a palr of handles 2 '2, that preferably correspond in shape and dimensions and project inv dia-.

metrically opposite directions from a suitable boss 3, which latter has inverted- L-shaped arms 4 4 proj ecting. from its ends, preferably in the same direction as and in a plane below the handles 2 2. Between its ends boss 3' is provided with a vertically-disposed opening 6, which when saidhandles are used fits over the upper extended end of the upper journal 7 of the hub f of the segmental rack,

and the lower extremities of the arms 4 4 rest upon the supporting-arms 7c 7c of the segmental rack and are provided with recesses or notches 5 5 or are bifurcated to. enable said extremities-to straddle and embrace the upper edges of arms K K, as shown. In the drawings of my aforesaid Patent N 0. 768,342 the hub f is shown to be journalednn the studs. In order to prevent end play of the handles 2 i be dispensed with and suitable provision for centering the handles be otherwise provided, although I desire it to be understood that such centering devices are not absolutely essential and can be dispensed with altogether. It is also possible for one of the arms 4 and one of the handles 2 to be dispensed with, although I much prefer the use of two of each.

I prefer to start the machine going by revolving fly-wheel B and shaft 0., althou h this need not bedone, and then taking ho l of the hand-grasps 9 9 and work them back and forth so as to impart to the segmental rack E a rotary reciprocal movement,whereby the rack and pinion F actuates the rotary reciprocal shaft H. The rotary reciprocation of the rack E causes shaft on and drivewheel B to revolve continuously in one direction, and the momentum or inertia of the flywheel acts as a balance for and materially assists in the operation of the machine.

What I claim as new is 1. In a mechanical movement the combination with a continuously-revolving shaft, segmental gear disposed in substantially the same plane as and operatively connected to said shaft, a rotary reciprocal shaft engaged thereby, and devices removably connected to said segmental gear for actuating said movement.

2. In a mechanical movement the combination with a continuously-revolving shaft, segmental gear disposed in substantially the same plane as and operatively connected to said shaft, a rotary reciprocal shaft en aged thereby, and devices connected to saic segmental gear for actuating-said movement.

3. In a mechanical movement the combi nation with a continuously-revolving shaft, a rotary reciprocal shaft, asegmental gear engaging said rotary reciprocal shaft, and a rockin yoke having a segmental rack engaged by said continuously-revolving shaft, of devices removably connected to said gear for actuating said movement.

4. In a mechanical movement the combination of a continuously-revolving shaft, a rotary reciprocal shaft, rotary reciprocal meansfor operatively connecting said shafts,

and a handle pivoted at one end concentric to the axis of said means and provided with an arm which is removably connected to said means for actuating said movement.

5. In a mechanical movement the combination of a continueusly-revolving shaft, a rotary reciprocal shaft, means for op eratively connecting said shafts, and a pair of handles extending in opposite direction from a common boss that has projecting arms and is removably connected to said means for actuating said movement.

6. In a mechanical movement the combination with a continuously-revolving shaft, a segmental gear operatively connected thereto and a rotary reciprocal shaft arranged at ri h angles to and engaged by said segmenta l g ar, of a handle one end of which is piv oted in alinement with said segmental gear, and which handle has an arm projecting from its pivoted end adapted to engage said segmental gear to actuate said movement.

7. In a mechanical movement the combination with a continuously revolving slTilTj segmental gear operatively connected thereto, a rotary reciprocal shaft engaged thereby, and a pair of handles extending in opposite directions from a common boss which is pivoted in alinement with the axis of said segmental gear, and is provided with projecting arms that engage and are removably connected to said segmental gear for actuating said movement.

8. In a mechanical movement the combination with a continuously revolving shaft, a rotary reciprocal shaft, a segmental gear engaging said shaft, and a' rocking yoke having a segmental rack engaged by said com tinuously-revolving shaft, of a handle pivoted at one end in alinement with the axis of said segmental gear having an arm and removablyconnected to said gear for actuating said movement.

9. In a mechanical movement the combination with a continuously-revolving shaft, a rotary reciprocal shaft, a segmental gear engaging said shaft, and a rocking yoke having a segmental rack engaged by said continuously-revolving shaft, of a pair of handles extendin in opposite direction from a common boss WIllCh is pivoted in alinement with the axis of said segmental gear and is provided with projecting arms that engage and are removably connected to said gear for actuating said. movement.

In testimony whereof I have hereunto set my hand this 24th day of October, 1905.
